Provided is a communication apparatus including a first communication unit for performing communication using a carrier having a first frequency, a second communication unit having a plurality of antennas, for performing communication using a carrier having a second frequency, a first communication processing unit for processing a signal received by the first communication unit and causing to transmit a signal, and a second communication processing unit for processing a signal received by the second communication unit and causing to transmit a signal. The second communication processing unit includes a synchronization unit for specifying a start position of a second transmission request in which a plurality of transmission beam patterns are set in one packet based on information indicating reception initiation, and an automatic gain control unit for performing automatic gain control based on a first automatic gain control setting value.
Legal claims defining the scope of protection, as filed with the USPTO.
1. An electronic device comprising: a plurality of antennas; and circuitry configured to: control performing wireless communication using a first frequency; control performing wireless communication using a second frequency, the second frequency higher than the first frequency; identify a start position of a second received signal including a beam training field based on a synchronization information, the synchronization information based on a first received signal, wherein the first received signal is received via the first frequency and the second received signal is received via the second frequency; and conduct gain control for beam patterns indicated by the beam training field included in the identified second received signal via the plurality of antennas.
2. A communication apparatus comprising: a plurality of antennas; and circuitry configured to: control performing wireless communication using a first frequency via a first antenna of the plurality of antennas; control performing wireless communication using a second frequency via at least a second antenna of the plurality of antennas, the second frequency higher than the first frequency; identify a start position of a second received signal including a beam training field based on a synchronization information, the synchronization information based on a first received signal, wherein the first received signal is received via the first frequency and the second received signal is received via the second frequency; and conduct gain control for beam patterns indicated by the beam training field included in the identified second received signal.
3. The electronic device of claim 1 , wherein the second signal is received with a predetermined no signal period.
4. The electronic device of claim 3 , wherein the beam training field includes a plurality of beam patterns, and the predetermined no signal period is set between the plurality of beam patterns.
5. The communication apparatus of claim 2 , wherein the second signal is received with a predetermined no signal period.
6. The communication apparatus of claim 5 , wherein the beam training field includes a plurality of beam patterns, and the predetermined no signal period is set between the plurality of beam patterns.
